Need to Regain Write Permissions on External Devices

[Geekier]

I just tried following this tutorial here and failed hard.

Regrettably I got stuck mid way through and now I'm noticing a couple of problems with my external HDD I currently have mounted as well as when I try and mount my flash drive.

I used to have Read/Write abilities on my external HDD and now I only have Read. On top of this, when I try to eject any device my mac hangs and I can't even force eject them.

Here's a screen shot of what happens when I try to eject a device:

I'm running Snow Leopard 10.6.6 and if anyone knows how I can regain having default write permissions and ejecting devices I'd really appreciate it.

You could try in Disk Utility repairing permissions for the drive?

I had a similar issue like this, and it worked for me
